Description

Technical Field

[0001] This invention belongs to the field of blood collection equipment technology, specifically relating to a device for breaking off an infusion tube blockage valve, an intelligent blood collection instrument, and a breaking method. Background Technology

[0002] Blood banks are legally mandated institutions for collecting and providing blood for clinical use. Blood collection has specific operating procedures and is a specialized technique. The process involves using specially designed blood collection bags (generally sealed plastic bags, single or multi-bags containing preservation solution) in a hygienic, open environment. Using equipment with weighing and agitation functions, a certain amount of blood is collected from the donor through puncture. This process is crucial for controlling blood quality. Currently, before blood collection, nurses primarily use scattered handheld mobile terminals, conventional testing instruments, and manually filled paper registration forms to complete pre-sampling registration, physical examination, and confirmation. The data and information generated during this process are integrated into the blood center's management system through manual entry into the paper registration form or uploading data to the handheld mobile terminal. During blood collection, the process involves donor identification, disinfection and puncture, blood sample retention, blood collection, communication, and education. In most cases, the success of blood collection relies heavily on the nurse's familiarity with the operating procedures, their experience, and their work ethic.

[0003] In recent years, with the development and progress of technology, companies have successively launched automated intelligent blood collection devices. These devices can automatically complete blood sample retention and collection, simplifying the entire process and greatly improving efficiency. However, using these devices requires an infusion tubing, a section of which is equipped with a blocking valve. When sampling begins, this valve needs to be broken to allow blood flow. Because the tubing is flexible, manually breaking the blocking valve can be problematic. Excessive force may leave the valve intact, damaging the tubing; insufficient force may also prevent the valve from breaking. Therefore, designing an automated device to break the blocking valve in infusion tubing is a pressing technical challenge. Summary of the Invention

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] Please see Figure 1 and Figure 2 A device for breaking an infusion tube blockage valve includes a drive motor 1, a drive motor mounting base 2, and a drive motor lead screw 3. The drive motor 1 is fixed on the drive motor mounting base 2. One end of the drive motor lead screw 3 is connected to the drive motor 1, and the other end of the drive motor lead screw 3 is rotatably connected to a mating part 4 via a first screw 5. The mating part 4 is also connected to one end of a breaking mechanism 7. A rotating mechanism 8 is connected to the middle of the breaking mechanism 7, and the breaking mechanism 7 can rotate around the rotating mechanism 8. A pair of tube-breaking columns 71 are provided at the other end of the breaking mechanism 7. The tube-breaking columns 71 are symmetrically arranged at both ends of the breaking mechanism 7.

[0036] Specifically, the drive motor screw 3 on the drive motor 1 moves forward or backward in a regular manner, causing the mating part 4 to rotate around the first screw 5; then the mating part 4 drives the breaking mechanism 7 to rotate around the rotating mechanism 8, and finally causes the tube column 71 to swing, completing the entire breaking process.

[0037] Furthermore, a first rubber gasket 6 is provided at the rotatable connection between the first screw 5 and the mating part 4.

[0038] The addition of a first rubber gasket 6 between the first screw 5 and the mating part 4 can prevent wear and deformation at the rotating connection and extend its service life.

[0042] The rotation of the ball bearing 84 in the roller 85 causes the bushing 83 to rotate, thereby causing the breaking mechanism 7 to swing.

[0043] Please see Figure 1 A fixed bracket 9 is provided above the breaking mechanism 7. The rotating mechanism 8 passes through the fixed bracket 9 and the breaking mechanism 7 in sequence and is connected to the fixed bracket 9 and the breaking mechanism 7. The other end of the fixed bracket 9 is connected to the support plate 10, and the support plate 10 is fixedly connected to the drive motor mounting base 2.

[0044] By setting a fixed bracket 9 and a support plate 10, the breaking mechanism 7 can swing smoothly and avoid vertical vibration.

[0045] Furthermore, a second rubber pad 82 is provided at the connection between the rotating mechanism 8 and the fixed bracket 9.

[0046] A second rubber pad 82 is provided between the rotating mechanism 8 and the fixed bracket 9 to prevent wear and deformation at the rotating connection and extend its service life.

[0050] A breaking device 100 is located on both sides of the upper part of the intelligent blood collection device. The breaking device 100 is used to break the infusion tube blocking valve to facilitate blood flow.

[0051] The sample retention mechanism 101 is located on both sides of the middle part of the intelligent blood collection device, and the sample retention mechanism 101 is used to quantitatively collect blood from the infusion tube;

[0052] An automatic shaking mechanism 102 is located on both sides of the bottom of the intelligent blood collection device. The automatic shaking mechanism 102 is used to quantitatively collect blood from the sample retention device 101 and can prevent the collected blood from clotting.

[0053] An automatic weighing mechanism 103 is located at the bottom center of the intelligent blood collection device. The automatic weighing mechanism 103 is used to collect and weigh the blood in the sample retention device 101, thereby enabling quantitative blood collection.

[0054] The combined action of the breaking device 100, the sample retention mechanism 101, the automatic shaking mechanism 102, and the automatic weighing mechanism 103 in the intelligent blood collection device makes the entire blood collection process more efficient, intelligent, and convenient.

[0055] Please see Figure 1-4 A method for breaking a blocked valve in an infusion tube includes the following steps:

[0056] S1. Place the section of the infusion tube with the blocking valve in the middle of a pair of folded tube columns 71, and fix the infusion tube above the blocking valve in the locking mechanism 13.

[0057] S2. Set the operating parameters of the drive motor 1 so that the drive motor screw 3 on the drive motor 1 moves forward or backward in a regular manner, thereby causing the mating part 4 to rotate around the first screw 5; then the mating part 4 drives the breaking mechanism 7 to rotate around the rotating mechanism 8, and finally causes the pipe column 71 to swing, completing the entire breaking process.

[0058] Furthermore, in step S1, the position of the clamping mechanism 13 can be adjusted up and down to accommodate the clamping and fixing of pipes of different specifications.

[0059] The working process of an intelligent blood collection device of the present invention is as follows: A section of the infusion tube with a blocking valve is placed between a pair of tube-folding columns 71, and the infusion tube above the blocking valve is fixed in the locking mechanism 13; the operating parameters of the drive motor 1 are set so that the drive motor lead screw 3 on the drive motor 1 moves forward or backward regularly, thereby causing the mating part 4 to rotate around the first screw 5; then the mating part 4 drives the breaking mechanism 7 to rotate around the rotating mechanism 8, finally causing the tube-folding column 71 to swing, completing the entire breaking process; after the blocking valve in the infusion tube is broken, a portion of the blood flows along the infusion tube into the sample bag in the sample retention mechanism 101, and the needle at the front end of the sample bag is inserted into the sampling tube on the automatic shaking mechanism 102, collecting the sample tube for measuring blood parameters; another portion of the blood flows along the infusion tube into the sampling bag on the automatic weighing mechanism 103, thus completing the entire quantitative blood collection process.

[0060] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
